Invention ideas: Laser Cane for the blind (also electronic tags for household objects).

Ideas: Laser Cane for the blind (Based on the already existing laser distance measurer).

This would use the same technology as a laser distance measurer except that, rather than giving a visual readout, it would speak the distance from an object so that the blind person could hear it.

Ideas:  Electronic tagging of objects so that you never lose anything ever again.

If they put electronic tags on criminals and migrating birds and even pet collars then why aren’t there electronic tags that you can put on objects in your home so that you can find them when you lose them? Surely it would be easier to track a missing object in your home than a runaway criminal?
